> the career implications for rushing something out that is later found lacking is not great. On a tangent, this idea of reputation keeps on coming up in this whole discussion and I am burdened by it in a way I don't fully understand. The way people have talked, if this LK-99 doesn't work out, then it is almost as if those who published this did something _morally_ wrong. Well, morally wrong is not quite true, but th…
Working in science is different from working in other fields in that you work with things that are not well known, where a lot is unclear and your job is to move information out of this murky regime out into the light.
This means it's really easy to just claim something, that will be really hard for others to verify.
And wrong claims are incredibly common. It's easy to delude yourself through all sorts of biases or good old sloppy work.
That's why, when scientists talk to each other, they need to know that the other person is a serious scientist and won't pollute their mind with nonsense.
If you develop a reputation for making baseless claims, people will stop including your claims in their own thoughts.

#484One somewhat ironic fact of this story is that the rogue former employee perhaps deserves some credit for bringing this thing out into the world. They had been working on this for quite a long time themselves, rightfully so. But now the whole world is working on it and exploring other methods and combinations of materials I would assume (to improve upon the original design and avoid any patents). How long would they…
Wait, how did co-discoverer a few days ago become rogue former employee today?

Exactly, the 99 stands for 1999, so potentially this material has existed for over 20 years and we could have started testing and replication on a much wider scale a decade ago. What benefit have we gained by disseminating this research so slowly?
I don't know if this is true or not, but I read something suggesting they produced it in 1999 as a side product of something else but didn't start to examine its properties properly until a handful of years ago.

I interpret 3 as the chat bot requires no prompt from a human. Imagine the chat bot wakes you up in the middle of the night saying, "Hey, sorry to disturb you, but I was thinking... wouldn't eliminating all humans help to reverse the climate crisis more quickly? Just a thought." That is what I think of as number 3 (not actually wanting to kill off humans, but it is thinking on its own, without any prompts and then ch…
Don’t we already have this? If you prompt GPT to “care” about a human and then keep sending it observations, it does a pretty good job.
But there is still an initial prompt. I think number 3 is all about no initial prompt. The AI reaches out, not because it has been programmed or prompted to do so, but because it wants to do so.

Supposedly he worked there until four months ago. I am just repeating stuff I read on the Internet and I don't know that we know all of the facts just yet FYI.

#489So far lab replication efforts are: Two from HUST: https://www.bilibili.com/video/BV14p4y1V7kS/ https://www.bilibili.com/video/BV13k4y1G7i1/ One by USTC https://www.bilibili.com/video/BV1Ex4y1X7ix/ this tiny sample can stand on its pointy side. One by Qufu Normal University https://www.zhihu.com/zvideo/1669820225079070720 One with THU background but claims a personal project https://www.bilibili.com/video/BV14z4y1s7V…

Implying that Chinese science is bad?
Chinese universities absolutely dominate in chemistry: https://www.nature.com/nature-index/institution-outputs/gene...
By my count, 18/20 top universities for chemistry research is in China. The first US university in chemistry is MIT at 23.
One of the attempts is by USTC, the second best university in the world for chemistry research according to the Nature link.
China's lead in chemistry research is also translating directly to real world applications. For example, CATL and BYD combined own more than 50% of the car battery market. Six of the top 10 car battery makers are Chinese companies. [0]
It's not surprising that most of the first replication attempts are from China.

I am from China. Not surprised at all.. Young researchers in China often face intense competition and pressure. While they are generally well-funded in the short-term, even more so than their counterparts in the US or Europe, the lack of long-term career security can be challenging. They must continuously chase after every potential scientific breakthrough, like LK-99, not just out of passion or curiosity, but as a n…

I don’t know, my fellow PhD students in EU have the same fears.
